Pildiandur

Digitaalkaamera füüsiline detail, mis sisaldab pildi iga piksli asukohta. Iga pildipunkt jäädvustab sellele särituse ajal langeva valguse ereduse. Levinud anduritüüpideks on CCD (laengsidestusseadis) ja CMOS (täiend-metalloksiidpooljuht).

ISO tundlikkus

Kaamera valgustundlikkus, mis põhineb filmikaamerates kasutatava filmi ekvivalendil. Kõrgema ISO tundlikkuse korral saab kaamera kasutada lühemat säriaega, mis vähendab kaamera värinast ja nõrgast valgusest tingitud hägusust. Samas on suure tundlikkusega tehtud pildid tundlikumad müra suhtes.

JPEG (Joint Photographic Experts Group)

Digitaalsete piltide kaoline tihendusmeetod. JPEG-pildid on tihendatud, et vähendada nende failisuurust pildi resolutsiooni minimaalse vähenemise juures.

LCD (vedelkristallekraan)

Tarbeelektroonikas levinud ekraanitüüp. Selline ekraan vajab värvide esitamiseks eraldiseisvat tagavalgustust, nt CCFL või LED.

Makro

See funktsioon võimaldab teil teha lähivõtteid väga väikestest objektidest. Makrofunktsiooni kasutamisel suudab kaamera teravustada väikestele objektidele praktiliselt elusuuruses (1:1).

Mõõtmine

Mõõtmine viitab viisile, kuidas kaamera mõõdab säri määramiseks valgushulka.

MJPEG (Motion JPEG)

Videovorming, mis on tihendatud nagu JPEG-pilt.

Müra

Digitaalfotol olevad valesti tõlgendatud pikslid, mis ilmnevad valesti paiknevate või juhuslike eredate pikslitena. Müra tekib tavaliselt siis, kui pildistatakse kõrge tundlikkusega või kui tundlikkus pimedas kohas automaatselt määratakse.

OIS (Optiline pildistabilisaator)

Funktsioon tasandab pildistamise ajal reaalajas kaamera rappumist ja vibreerimist. Digitaalse stabilisaatoriga võrreldes ei toimu seejuures pildi kvaliteedi halvenemist.
